2. R.G. – 3/03/2006 PAF progress 2 Procedure for the on-going analysis (1/3) Outcome of the last meeting with R. Aymar & J. Engelen on 10/01/2006: - Instructions for preparing a contribution to the Open Symposium (Orsay, January 30 – February 1) => report published (“Preliminary accelerator plans for maximizing the integrated LHC luminosity”) - Requests for cost estimates and prioritization of the proposed actions => on-going analysis – goal & procedure presented today (3/03/2006)

3. R.G. – 3/03/2006 PAF progress 3 Procedure for the on-going analysis (2/3) Goals: - get estimates and planning from equipment groups - assemble results in synthetic format (typical presentation below)

4. R.G. – 3/03/2006 PAF progress 4 Procedure for the on-going analysis (3/3) Distribution of the tasks

5. R.G. – 3/03/2006 PAF progress 5 Progress and observations (1/2) - Consolidation: to be based on the consolidation programme managed by S. Baird (specific comment: a reasonable scheme of repair for the SPS magnet is proposed.Will be done during shutdown 2006/2007 by re-arranging priorities.) - Improvements: a number of actions are clear and have started being quantified (PS multi-turn ejection, impedance reduction of SPS kickers, PS longitudinal damper), part is unclear (depends on results of machine studies). - Linac4 & PSB: well advanced technical design. Solid base for a first cost estimate assuming no external contribution. Quantification started. - LHC IR: complex because of absence of experimental experience (!) / multiplicity of possibilities / diverging opinions of experts. Multiple interviews with many experts & group leaders to request views on procedure, planning and estimates of resources.

6. R.G. – 3/03/2006 PAF progress 6 Progress and observations (2/2) - PS successor: list of basic parameters for PS2 (normal conducting) is established using some “educated guesses”. Contacts with equipment groups have started. Parameters for PS+ (superconducting) in preparation. - SPS successor: parameters for SPS+ in preparation. - Future facility: based on “roadmap” established by neutrino community (ISS: 2005-2006, Design Study: 2007-2010, Technical Design: 2011-2013, Construction: 2014-…). Difficulties: need to prepare for submission of a DS proposal to the EU during 2006 (degree of CERN involvement ?) + too limited data to ask for estimates of cost of facility.

7. R.G. – 3/03/2006 PAF progress 7 Summary of observations Technical investigations are not finished  precise parameters are not yet clear + Short time scale forces to simplify the questions  specific options are selected « arbitrarily » + Parallel investigations limit the debate  limited accuracy Is it in line with the expectations of the Direction ?

8. R.G. – 3/03/2006 PAF progress 8 Planning Refinement of the distribution of tasks: February 6 Presentation to the Direction – request for feedback: end February  First sets of results + preliminary list of priorities: March 13 ‘ Draft: April 17  Report: May 22 Is it in line with the expectations of the Direction ?
